Protel Trial versions for 98, 99 and 99 SE offer extensive design in both the form of schematic representation and mnemonic coding for Xilinx products and a host of other FPGA and PLD. Under PLD Design section, you will have to select Xilinx GA3000 for developing for the XC3020. Of course, the downloading of the compiled binary into the FPGA is another story. You will have to make an interface yourself and connect to a parallel or serial port, and write your own code to download it. You probably will get away with writing it in QBasic or some other scripting Language. Also, the trial versions only work for 30 days, but are full functional. You can find some cracks on the net to extend the time indefinitely. Please note however that the trial downloads are large (30-60MB), and unless you have a fast link, it will take a while to download. You can download the 99 SE Trial Version from the Protel Site (http://www.protel.com). I have the earlier Trial Version 99 SP1, if you should prefer. Please let me know and I will place it on a website for download (remember that they are large). PS! Send me a private message if you require some special favour, if you catch my drift!

The trial version of Protel will let you enter a design -- but you still need something to map (place and route) the design for the Xilinx device. I thought I'd heard that the Xilinx Foundation Base was not too expensive. Foundation Base has a schematic editor and (I think) VHDL synthesis using FPGA Express. 73 Hamish (who works with FPGAs for a living) -- Hamish Moffatt VK3SB --- You are currently subscribed to ss as: lyris.ss@tapr.org To unsubscribe send a blank email to leave-ss-6751T@lists.tapr.org From bounce-ss-6751@lists.tapr.org Fri Sep 1 07:24:23 2000 Received: from lists.tapr.org (lists.tapr.org [204.17.217.24]) by tapr.org (8.9.3/8.9.3/1.13) with SMTP id HAA02660 for ; Fri, 1 Sep 2000 07:24:21 -0500 (CDT) X-Sent: 1 Sep 2000 12:19:32 GMT Message-ID: From: "Fernando M.

But they're not as useful as an FPGA like the 3020 (which the original question was about).

No, when I said the PLD section, it is becuase it is all under that name, under the PLD menu option. 1) Start a Schematic File 2) Select the Menu PLD -> Configure 3) Select the Target Device under the options Tab. In this case chose XILINX ga3000 for the XC3020 4) Select the output format (eg. JEDEC, POF, PRG, HEX, etc.) 5) Select output options as required. 6) Now draw your design using the virtual sub-components as required fromor the Xilix library 7) Compile it using (PLD -> Compile) This will also produce a CUPL file which is then compiled in to the final output format. 8) Use the simulations to test ( PLD -> Simulate) 9) View the Output file before exporting it to a DOS File. In the Protel 99 SP1 Version, under the examples directory, there should be a Xilinx Sub-directory with examples, of which one is for the XC3020PC68 [XILINX 3K Series.ddb]. (This if you installed the Xilinx Section when you were prompted when you first installed the package) For more details consult the On-line Help File or the Protel Documentation (also available in PDF format on the Protel website). You can also download the Xilinx libraries from their site.

No, Compiling only sets up for the internal mapping/routing of the FPGA (by converting the schematic representation into the CUPL and then the final output format). The external design can be set-up in a master schematic (which would have a link to the FPGA schematic), where you place all the other components, and from which you would make the netlist for the PCB. For auto-routing and placement, you would start a PCB document, define all the keep-out areas, and use the net-list from the previous step to produce the routing, placement, etc. Of course, I am making it short and simple here. Use the examples, or follow the tutorials available on the Protel website.

I can see that you're new to this. When you receive spam, NEVER reply to the "remove" address. The spammers are hoping that you will be unknowledgeable enough to do this. At best, your mail will just bounce. At worst, you'll furnish the spammer with your authentic, live e-mail address, which will be added to spam lists that are sold on CD-ROM. You'll never get rid of the spam what that's happened. Don't visit the URL, either. In many cases (though not when the spam is sent to the list), the URL can be jiggered to verify your e-mail address also. The correct thing to do is complain to the source's ISP(s). (There may be more than one, since the mail will often come from a throwaway dial-in account while the Web site is hosted elsewhere and the reply addresses are at others.) What's more, if the spam was broadcast through an open relay, it's a good idea to send it to the MAPS RSS so that the relay is blocked. See cauce.org and maps.vix.com for more info. It's unfortunate that this list is handled by Lyris, which "launders" the headers so that members of a list can't track the spam back to the source. However, it ought to be possible for the moderator to reject mail which does not come from a known member of the list. I'm not sure why s/he has not enabled this feature. --Brett Glass --- You are currently subscribed to ss as: lyris.ss@tapr.org To unsubscribe send a blank email to leave-ss-6751T@lists.tapr.org From bounce-ss-6751@lists.tapr.org Sun Sep 10 15:05:30 2000 Received: from lists.tapr.org (lists.tapr.org [204.17.217.24]) by tapr.org (8.9.3/8.9.3/1.13) with SMTP id PAA05540 for ; Sun, 10 Sep 2000 15:05:29 -0500 (CDT) Message-Id: X-Sender: brett@localhost Date: Sun, 10 Sep 2000 14:04:03 -0600 To: "TAPR Spread Spectrum Special Interest Group" From: Brett Glass Subject: [ss] Re: FREE Investor's kit--more SPAM to get rid of Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" List-Unsubscribe: List-Software: Lyris Server version 3.0 List-Subscribe: List-Owner: X-List-Host: Tucson Amateur Packet Radio Reply-To: "TAPR Spread Spectrum Special Interest Group" X-Message-Id: <4.3.2.7.2.20000910140327.0548c100@localhost> Sender: bounce-ss-6751@lists.tapr.org Precedence: bulk Oops...

(AKA Cal Eastern) www.cal.com ??? They have a couple of mixers that would do the job. There is also an LNA that works very well from VHF to at least the 900 MHz band. If your are manufacturing, you will want to look at the "TB" size, as the other larger sizes are on their way out. The "tb" size is very small. I think it is equivalent to a six lead SOT 363. (SOT663 ??). Now the good part is they have developers, or evaluation boards, that you can get. They make the engineering task much quicker. You will need a local oscillator. If your task is broad band, look into a SAW oscillator. RFM has a circuit and list of almost a zillion frequencies in their catalog. RFM.com, not to be confused with RFMD.com RF Microdevices (RFMD) also has downconverter ICs, and probably the whole thing on two evaluation boards. Their stuff is great, at your frequency, once it is in the circuit. Putting their ICs in a circuit is another matter. They have unprotected CMOS gates. Some of RFMDs stuff is "pushing it" at 900 MHz tho. In that band you need to call them & get the lowdown from the "area manager." If you do use RFMD, a trick is to put 10K to ground on every input & output pin before you insert the IC in the circuit. Then use lots of solder paste. This effectivly shorts the CMOS gate during assembly.

I am writing a code in Matlab to do direct sequence ss using a simple BPSK mod/demod scheme. I'll number some of the steps I am doing and you could tell me if I am doing something wrong: 1) I have a pseudo-random sequence of length 7 (+/-1's). 2) create message to send, of +/-1's, and repeat each one of them 7 times so that the ratio of their periods is 1:7 3) I multiply the message by the pn sequence 4)perform modulation 5)add different levels of noise (send through channel) 6)perform demodulation 7)multiply back by the pn sequence 8)compare received message to initial message 9)calculate ber This code doesn't seem to work for me.

Also, I noticed that you did not make any mention of syncronasation of the stream with the PN sequence for demodulation. I assume you have all the data already in sync. If not, you will have to add that part so as to sync the incoming stream with the PN sequence in order to retrive the data! Note also that the data rate is not usually the same as the PN rate (eg. PN rate could be 4x data rate). You probably already doing that, but since you did not mention it, I wondered! In the case of PN = 4x data rate, a PN sequence of 7 bits is a bit short for real-life practical SS. The best would be for you to send more details. You can send it directly to me if you prefer (fmi@carreiro.com) Fernando Carreiro (fmi@carreiro.com) ZS6BLF ----- Original Message ----- From: "Jane Johnson" To: "TAPR Spread Spectrum Special Interest Group" Sent: Friday, September 15, 2000 7:13 PM Subject: [ss] direct sequence ss code Hi, I am a student at UC Davis. I just started learning about ss. This question is probably too elementary for the type of things you do, but if someone could help me I would appreciate it very much. I am writing a code in Matlab to do direct sequence ss using a simple BPSK mod/demod scheme. I'll number some of the steps I am doing and you could tell me if I am doing something wrong: 1) I have a pseudo-random sequence of length 7 (+/-1's). 2) create message to send, of +/-1's, and repeat each one of them 7 times so that the ratio of their periods is 1:7 3) I multiply the message by the pn sequence 4)perform modulation 5)add different levels of noise (send through channel) 6)perform demodulation 7)multiply back by the pn sequence 8)compare received message to initial message 9)calculate ber This code doesn't seem to work for me. If you are interested in the files I can send them to you or if you know of a code I could look at, preferably witten in Matlab,I would appreciate any help.

It turned into a heated discussion where; One gentlemen thought my ideas belonged in the networking sig. I see packet mentioned several times below. So I am re-posting this. Also waiting to see reports on anyone else using part 15 WLAN devices. Spread Spectrum SIG This mailing list is for the discussion of topics related to the application of spread spectrum communications technology to amateur packet radio networking. The emphasis of this SIG is on the technology of spread spectrum rather than regulatory or political issues. Suitable topics include: �New SS chipsets and modem products, and their applicability to the amateur service �Performance reports on existing products (e.g., Part 15 WLAN devices) �Relative merits of direct sequence, frequency hopping and hybrid approaches in amateur SS applications �Use of CDMA and other multiple access techniques to build packet radio LANs/MANs �Dealing with shared allocations and interference in the UHF and higher amateur bands �Proposals for development projects in amateur packet SS �Sources of SS information on the Internet and elsewhere: books, articles, web pages, FAQ files, etc Steve Lampereur, KB9MWR http://www.qsl.net/kb9mwr/wireless.html --- You are currently subscribed to ss as: lyris.ss@tapr.org To unsubscribe send a blank email to leave-ss-6751T@lists.tapr.org From bounce-ss-6751@lists.tapr.org Sat Sep 30 00:54:29 2000 Received: from lists.tapr.org (lists.tapr.org [204.17.217.24]) by tapr.org (8.9.3/8.9.3/1.13) with SMTP id AAA11174 for ; Sat, 30 Sep 2000 00:54:29 -0500 (CDT) Message-ID: In-Reply-To: References: Date: Fri, 29 Sep 2000 22:51:48 -0700 Reply-To: "TAPR Spread Spectrum Special Interest Group"
